B1\n- Explains the consequence of this change, such as single-person households being less water-efficient because shared use of appliances like washing machines is reduced, or a larger population increasing the total number of domestic consumers. M1\n- Provides a fully developed link to the increase in overall water demand, showing how this elevates the national per capita consumption rate or dramatically escalates the daily volume of water required.
